Imgur HELP

My hands and feet have been red, swollen, and PAINFUL for four days now. They felt weird Sunday night after a date with my girlfriend, and by mid next day they were full-fledged inflamed. They've remained about the same since. They don't itch at all. I don't take any medications, have never had any allergies, and have always been blessed with good health. I went to the doctor today and they all insisted on telling me that I had frostbite. I would normally not argue with a medical professional, but they didn't look into anything else beside their first glance of my hands. They insisted on telling me that I must have spent some time in the cold and not even realized it. Really?! When I'm sitting there telling them that I've been indoors for the last week? I don't have blisters, my hands don't tingle or go numb, and I haven't lent myself to any sort of abnormal temperatures. The strangest thing is that my feet mimic my hands. If frostbite is common without any of those things, I am open to the idea. I just worry that I may have something more serious going on, and the complete lack of interaction from the doctors left me with more questions than answers. The picture may not do it complete justice, but it's very noticeable and my feet are the same. If anyone has any insight it would be much appreciated
